A triad assembly, with a photosensitizer ( P ) linked in tandem to a water oxidation catalyst ( D ) and a hydrogen evolving catalyst ( A ).

Antimicrobial photodynamic therapy is the process in which light and photosensitizer are used to destroy cell membrance of the bacteria by the action of reactive oxygen species and singlet oxygen.
23.
Photooxygenation reactions are initiated by a photosensitizer, which is a molecule that enters an excited state when exposed to light of a specific wavelength ( e . g . dyes and pigments ).
24.
And, the excited electron that had resided on the functional ligands of photosensitizer passes through the ancillary ligands to the catalytic center, which becomes a one-electron reduced ( OER ) species.

In this study, the therapeutic effect of PDT using the synthetic photosensitizer pheophorbide a ( Pa-PDT ) was examined in AT-84 murine oral squamous cell carcinoma ( OSCC ) cells.
26.
The oxidized photosensitizer ( S + ) accepts electrons from the I " ion redox mediator leading to regeneration of the ground state ( S ), and the I " is oxidized to the oxidized state, I 3 ".
27.
PIT treatment avoids the side effects problem through the creation of a targeted-photosensitizer, which involves two components : a monoclonal antibody ( mAb ) which recognizes specific proteins on the surface of cancer cells, and a non-targeted photosensitizer.

This type of cell still depends on a semiconductor ( such as TiO 2 ) for current conduction on one electrode, but with a coating of an organic or inorganic dye that acts as a photosensitizer; the counter electrode is a platinum catalyst for H 2 production.
30.
As with water oxidation catalysis, not only fully artificial systems have been idealized : hydrogenase enzymes themselves have been engineered for photoproduction of hydrogen, by coupling the enzyme to an artificial photosensitizer, such as [ Ru ( bipy ) 3 ] 2 + or even photosystem I.
